Environmental drivers of the decline of the fen orchid, Liparis loeselii

The paper identifies nutrient status and hydrology as key factors driving the decline of the fen orchid, Liparis loeselii, with eutrophication and drainage being the primary causes.

Rapid and continuing regional decline of butterflies in eastern Denmark 1993-2019

The paper tracks butterfly population declines in eastern Denmark from 1993-2019, finding significant regional extinctions and continued declines despite protected areas.

Scrub encroachment promotes biodiversity in wetland restoration under eutrophic conditions

The paper investigates how scrub encroachment affects biodiversity in wetlands under eutrophic conditions, finding that it can enhance species richness and conservation value.

Simple attributes predict the importance of plants as hosts to the richness of fungi and arthropods

The paper investigates how plant attributes predict the richness of associated fungi and arthropods using link scores derived from plant-consumer interaction databases.

Treated like dirt: Robust forensic and ecological inferences from soil eDNA after challenging sample storage

This study assesses how storage duration and temperature affect soil eDNA metabarcoding results, finding minimal changes under 20°C for up to 28 days.

Quaternary climate change explains global patterns of tree beta-diversity

The paper examines how Quaternary climate change influences tree beta-diversity globally, finding temperature changes since the Last Glacial Maximum strongly affect turnover and nestedness components.

Paleoclimate and current climate collectively shape the phylogenetic and functional diversity of trees worldwide

The paper maps global tree diversity patterns and shows that both current and ancient climates influence tree species richness, functional, and phylogenetic diversity.

Half of the world's tree biodiversity is unprotected and is increasingly threatened by human activities

The paper identifies priority areas for global tree conservation and finds that half are unprotected and face human threats.

Multi-taxon inventory reveals highly consistent biodiversity responses to ecospace variation

The paper uses an ecospace framework to analyze multi-taxon biodiversity across 130 sites in Denmark, finding consistent responses to environmental variation and highlighting the role of organic matter for fungi and insects.

A systematic survey of regional multitaxon biodiversity: evaluating strategies and coverage

The paper evaluates a sampling strategy for regional multitaxon biodiversity, finding high coverage and spatial variation in species richness across Denmark.

Man against machine: Do fungal fruitbodies and eDNA give similar biodiversity assessments across broad environmental gradients?

This study compares fungal biodiversity assessments using eDNA-metabarcoding and fruitbody surveys across environmental gradients, finding convergence in some metrics but differences in others.

Predicting provenance of forensic soil samples: soil DNA predicts habitat and environmental properties

The paper uses soil eDNA to predict environmental conditions, habitat types, and geographic regions, showing high accuracy for some variables but limitations in others.

Vascular plants are strong predictors of multi-taxon species richness

The paper tests if vascular plants predict multi-taxon species richness and finds they explain 48% of total species richness variation when combined with bioindicators.
